S90.81 Abrasion of foot

Name of the Condition

• Abrasion of foot

Summary

An abrasion of the foot is a superficial injury to the skin caused by friction or scraping, resulting in the removal of the outermost layer of skin. This type of injury is typically minor but may cause pain, redness, and minor bleeding. Abrasions are common in areas exposed to friction, such as the heel, sole, or toes, and often heal without significant complications.

Causes

Abrasions of the foot commonly result from direct contact with rough surfaces, such as pavement, gravel, or carpet, during activities like walking, running, or falling. Other causes include friction from ill-fitting footwear, repetitive rubbing during sports, or accidental scraping against objects. The injury occurs when the skin is rubbed or scraped, leading to the loss of the epidermis.

Risk Factors

• Participation in activities with high risk of foot trauma, such as hiking, sports, or manual labor.
• Wearing poorly fitting or worn-out shoes that increase friction.
• Environments with rough or uneven surfaces, increasing the likelihood of scraping.
• Pre-existing skin conditions or reduced sensation in the feet, which may impair awareness of injury.

Symptoms

• Pain or tenderness at the site of the abrasion.
• Redness, swelling, or minor bleeding.
• A raw or grazed appearance of the skin.
• Possible crusting or scabbing as healing progresses.

Diagnosis

Diagnosis is typically made through a physical examination of the affected area. Healthcare providers assess the extent of skin damage, check for signs of infection, and evaluate the surrounding tissues. In some cases, imaging may be used to rule out deeper injuries, though this is uncommon for uncomplicated abrasions.

Treatment Options

• Cleaning the wound with mild soap and water to remove debris.
• Applying an antibiotic ointment and covering with a sterile dressing to prevent infection.
• Keeping the area dry and protected during healing.
• Pain relief with over-the-counter medications if needed.
• Avoiding further friction or pressure on the injured area.

Prognosis and Follow-Up

Most abrasions heal within 1–2 weeks with proper care. Follow-up may be recommended if signs of infection develop, such as increased redness, pus, or fever. For uncomplicated cases, routine monitoring at home is usually sufficient.

Complications

• Infection, particularly if the wound is not properly cleaned or covered.
• Delayed healing due to repeated friction or pressure.
• Scarring, especially if the abrasion is deep or becomes infected.

Lifestyle & Prevention

• Wear appropriate footwear, such as closed-toe shoes or protective gear, during high-risk activities.
• Avoid walking barefoot on rough or unfamiliar surfaces.
• Use moisturizers to keep skin supple and reduce friction.
• Inspect feet regularly for early signs of injury, especially in individuals with reduced sensation.

When to Seek Professional Help

Seek medical attention if the abrasion is deep, shows signs of infection (e.g., pus, spreading redness), or does not heal within two weeks. Also, consult a provider if there is excessive bleeding, severe pain, or signs of underlying tissue damage.

Tips for Medical Coders

When coding for an abrasion of the foot, use ICD-10-CM code S90.81. Ensure documentation specifies the anatomical location (e.g., heel, sole) and any associated factors, such as infection or delayed healing, to support accurate coding. Note that this code is specific to the foot and should not be used for abrasions of other body parts.
